  • How fire can be tamed

    Combustion dies at the interface between breathable air and macroscopic pieces of certain involatile fuels. If fed only them, in a compressed oxygen chamber, it makes an almost sunlike flame that cannot run wild. If upon dilution to manageable coolness the ash drops to the chamber bottom, and from there can be removed without the diluent, true harnessbrokenness is possible. Excess oxygen can be ...
